Figure 2: Microphotograph (a; H and E stain, original magnification × 10) of sections from soft-tissue mass shows mitotically active primitive tumor cells (solid arrow) arranged as tubules (dashed arrow) at places amidst a loose spindle cell mesenchymal stroma (solid filled arrow). Immunohistochemistry shows a positive expression of WT1 protein in the primitive cells and tubules (b) along with PAX8 expression in the renal tubules (c)
